' invention relates to a fluid control device.

The general object is to provide a novel, fluid pressure operated, timecontrolled, valve by means of which the passage of fluid through aconduit may be controlled.

A more specific object of my invention is to':.

provide anovel valve for controlling passage of fluid through a conduitand wherein the passage Y of fluid through the conduit controlsthe'valve.

Another object of the invention is to provide a time controlledvalveincluding a novel regulating member.

A further object of the invention is to provide "a novel time controlvalve having a novel check valve. v A further object of the invention isto provide 7 a time control valve. including a piston and cylinder andwherein novel means is provided for bleeding the cylinder.

- An additional object of my invention is to provide a novel remotelycontrolled time valve.

Other objects and advantages of the invention will be apparent from thefollowing description taken in connection with the accompanyingdrawings, wherein:

Fig. 1 is a top plan view of the features of my invention;

Fig. 2 is a section taken on line 22, Fig. 1; Fig. 3 is a section takenon line 3-3, Fig. 1;

a'valve embodying disk is held in placeby a nut 26 on a bolt 21 whichpasses through an aperture 28 in the valve body 22. The bolt 21 servesto hold a piston cap member 29 in place.

Between the cap member and body 22 I arrange upper and lower packings 30and 3| which are separated by a plate member 32.

I Thevarious packing members may be made of rubber, artificial rubber orsimilar material and the various members of the valve and body may bemade of suitable material, for example brass and certain of the partsmay be suitably plated, as for example with hard chromium to reduce wearand corrosion. r r r The cap member l5 includes an aperture 33 inwhichthestem 34 of a regulating member is rotatably and slidablyarranged. At its lower end "the stem 34 includes a-fiange 35 whichengages theadjacent'face 36 of the cap member l5. The engaging faces areplanar and the parts are held together by a resilient deviceindicatedgenerally at 31. 7 As shown, the resilient device includes an outerretainer member 38 and an inner retainer member-39 which slides'withinthe retainer 38.

' The member 38 is provided with opposed slots 40 in which tongues' llon the member 39 are arranged. A coiledspring 42 is arranged within themembers 38 and 39 and the assembled device Fig. 4 is a section taken online 4-4, Fig. 2; {.330

Fig. 7 is a. section taken on line 1-'l, Fig. 1, and

on an enlarged's'calej and p a r Y Fig.8'is a diagrammatic plan'viewshowing my 5 improved water distribution system. 3 r Referring to thedrawings by reference characters. I'have shown my invention as embodiedin a time valve which is indicated generally at l0. As shown, the device[0 includes a hollow cylin;

drical body ll, having'an internal bore [2 and having a closed bottomI3. Opposite the closed ,bottoirl I3, the body includesa flange 14 whichis. engaged by a cap enclosure member l 5 with the parts held togetherby bolts l5.

, I ovided, with fluid outlet 11' and a fluid inlet l8 both of, whichare adapted to be connected to suitable pipes.

The lower portion of'the body includes a valve seat forming partition [9which includes a valve Y seat 20; 'Within the bore I2 I arrange asliding valve indicatedfgenerally at 2|. Asshown this valve includes ab'ody'22 having a gasket 23 engaging the lower endjthereof.'Th'e'gasket' 23 engages a bead 24 surrounding the valve seat.

is mounted in a recess 43 in the cap member and about [the stem. v Themember 38 engages the bottom ofthe. recess and the member 39 engages jthe lower face of a head 44. The head 44 has an aperture 45 which fitsover a reduced portion 45 onthe stem 33 and is held in place by'a screw41.

The "construction is such that the regulating member may be rotated-thusrotating the stem 33 or the regulating member may be depressed bypushing down on the head 44;

The body I l is provided with a conduit 55 which at one end as at 5|opens into the body ll below the partition. The upper portion of theconduit includes an enlarged portion 52 which has a shoulder 53 at thelower end thereof. The por- ,tion 52 is cylindrical and in this portionI ar- "rangea check valve '54 (Fig. 4) which is shown as hexagonal toprovide a passage for fluid through the channels 55 when the check valveis in the position shownin Fig. 1. The cap memher includes a conduit 56smaller than and aligned with the conduit portion 55 thus providin'gthe'shoulder 51 against which the upper end 1 of the check valve 54 engageswhen the valve is infits upper "position.

" "The conduit 56 includes a'downwardly extending portion 58 which whenth flange 35 is in one position aligns with a hole 59 in the flange. Theupper surface of the flange 35 includes a metering slot 60 which isgraduated from the hOle 59 and is arranged coaxial with the axis of thestem 34. The groove 60 is deepest adjacent the hole 59 and is ofdecreasing depth as it recedes from this hole. The construction is suchthat when the hole 59 aligns with the cpnduitportion 58 free passage 'isallowed to the interior of the cylinder. 7

When the flange 35 is turned, fluid passes from the conduit portion 58to the groove 68 and thence through the groove 68 to the hole 59 andthus passage is restricted from theconduit 58. When the extreme end ofthe groove era-liens with' the conduit portion 58 a minimum iam untiofliquid passes from the conduit portion, 58 into the cylinder.

Assuming the cylinder is bled by turning the flange 35 to align theaperture 63 therein with the bleed aperture 6|, the fluid enters theinlet aperture l8 and urges the piston valve 2! upwardy, therebydischarging fluid in the upper portion of the cylinder through the bleedaperture 6l. During the operation, the check valve 54 may be forcedagainst its seat by the fluid which passes through "the conduit 50.

,4 The lifting of the valve 2| opens the valve seat or the orifice 20and allows free passage of fluid Ithrough the outlet aperture l1. Assoon as the fluid ceases to flow from the bleed aperture 62,theiiper'ator closes the bleed valve by turning the head fl to thedesired position with reference to the indicia T4 so that the desiredPortion of the "groove 60 is opposite the conduit 58.

Thi's operation. may Ice-"continueduntil all of the area covered bysth'e -sprinkler' 96 .has beensprinkled, whereupon the last of the valves 95 is-closed. In performingthis operation, the operator may bleed the device I by depressing thestem 34 or by rotating this stem instead of using the bleed valve 61.

When the sprinklers IOI are to be operated, one of the associated valvesI00 is opened and the remote bleed valve I03 is opened for a period andthen closed. After a period of time the device |0 will close the valvetherein and the operation may be repeated. The other valves I00 may besimilarly operated.

Thus it will be seen that my system permits an attendant to look afterother duties while the sprinkling is being done and also permitsoperation of the system remotely from the valve device I0.

When the valve is operating for long periods of time, the small portionof the metering slot 60 is employed and isvery sensitive to adjustment.With my construction, by bleeding through the conduit 65, the adjustmentof the metering slot 60 need not be altered each time the valve isactuated so that the correct adjustment remains.

The arrangement shown whereby the valve closes against the flow andpressure and with the conduit 50 leading to the inlet permits my valveto be used to replace the usual sprinkler angle valve.

In some sprinkling systems small spray heads are employed and theseoperate but a few minutes at a time. In other systems large rotary headsare employed which are operated at a considerable length of time. Withmy construction the attendant may readily change from the long period tothe short period and vice versa by shifting the metering valve 82 fromone position to the other and the metering valve is also of considerableuse in certain commercial installations.
